Speaking — Convince me! With a partner, prove that 3/6 = 1/2 in two different ways (for example, a picture and a rule). Then take turns being the skeptic who asks, “How do you know?”
- Draw or fold a model
- Use the multiply-both rule
- Use a number line
- Use a set (beads or counters)
- How do you know the parts are equal?
- Would that work for any fraction?
- Can you show me another way?
- Convince your partner that 2/3 is NOT equivalent to 3/4.
